A nurse is working with a client who routinely lies to staff, refuses to comply with unit rules, and shows no remorse for the people they have harmed with their behavior. These behaviors best describe what personality disorder?

A: Antisocial Personality Disorder is characterized by a pervasive pattern of disregard for the rights of others, deceitfulness, impulsivity, irritability, aggression, and lack of remorse. The behaviors described in the question—lying, non-compliance with rules, and lack of remorse—are hallmark symptoms of this disorder. B: Narcissistic Personality Disorder involves a pattern of grandiosity, need for admiration, and lack of empathy. While individuals with this disorder may also lie and manipulate, the primary features are their self-centeredness and need for admiration, which are not the main focus of the behaviors described. C: Histrionic Personality Disorder is characterized by excessive emotionality and attention-seeking behavior. Individuals with this disorder may be dramatic and manipulative, but the behaviors described in the question are more indicative of antisocial traits rather than histrionic traits. D: Avoidant Personality Disorder involves a pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Individuals with this disorder are typically very anxious and avoidant of social interactions, which does not align with the behaviors described in the question.
